The interpretation of dreams has been a favorite activity of people for as long as we have had recorded history. Some of these dream interprets have become famous, and some, like the European psychologist Sigmund Freud, felt that all dreams have meanings which relate to our personal relationships with family members and friends.
    Good dreams include those in which we see ourselves succeeding in some difficult or pleasant activity such as singing, dancing, talking with our friends, or experiencing the happiness which may not occur in our waking hours. Many persons report dreams of competing in athletic competitions or music competitions. The performance in these events can go beyond anything we might experience in reality. Who among us has not dreamed of spending pleasant hours with our real or imaginary lover, enjoying his or her company in ways known only to those who have loved? Interpreters of such dreams give varied meanings, most of which are probably not very reliable. But, we often awake from good dreams in a good mood, rested and ready to face the day.
    Bad or unpleasant dreams include those which frighten us, recall unpleasant experiences from our lives, or present problems for which there is no evident solution. Dreams of failing an exam at school, dreams of losing a job or a good friend, dreams of accidents or death of a loved one in our family, etc. are unsettling and not easily understood. Some dream experts believe these dreams are now a threatening way to face a problem from real life. They give us a way to deal with the problem so that we may find it less stressful in our waking hours.
